TK6700 Arc Welding Machine Comprehensive Calibrator
TK6700 is a comprehensive AC/DC welding machine power calibrator, integrating a high-current precision measurement module and a resistive load. It enables accurate calibration of welding machine current and voltage without disassembling the equipment, making it ideal for on-site maintenance and testing. The device supports maximum measurement currents up to 1 kA and offers selectable accuracy classes of 0.05 and 0.1, providing versatility for various industrial welding machines.
With high-resolution voltage and current measurement capabilities, TK6700 ensures precise verification of welding machine outputs. Its low temperature coefficient minimizes errors due to environmental changes, while its robust design allows reliable operation in industrial environments with variable temperature, humidity, and electrical interference.
The device features a user-friendly digital interface and supports computer program control via USB and LAN, enabling automated testing, data logging, and integration with quality management systems. TK6700 combines precision, portability, and protection mechanisms—including overload, short-circuit, and over-temperature safeguards—for safe and efficient calibration.
